RZComet62

I've got a 62 comet with the 170 cu engine and had a leaky sending unit so I bought a replacement gas tank/sending unit from 1a auto and replaced it (the tank had seen better days as well). Car was running well prereplacement with a new fuel pump, but now no gas is getting to the engine (the fuel filter looks totally dry) .. I'm assuming I got a bad sending unit and will now have to drain the tank and pull it out.. but was wondering if there was anything else it could be? thanks for any help anyone can provide .. https://www.1aauto.com/ford-falcon-mercury-comet-fuel-tank-kit-diy-solutions/i/1afrk00063/844031/1962

I have a 62 Comet 2dr with bench seats in nice shape, but the hardware to mount the seats appears to have not been transferred along with the car and is missing in action. Any clues on where to find something to let me bolt the seats in?
